revlog: return 0 for the fast_rank of nullrev
By convention, the rank of the null revision is 0. This particular revision is
never "physically" stored in the changelog, so it is a special case.
For consistency, the value `None` is still being returned for revlogs which do
not store the fast_rank property for any revision.

#require no-reposimplestore
Testing the case when there is no infinitepush extension present on the client
side and the server routes each push to bundlestore. This case is very much
similar to CI use case.
Setup
-----
$ . "$TESTDIR/library-infinitepush.sh"
$ cat >> $HGRCPATH <<EOF
> [alias]
> glog = log -GT "{rev}:{node|short} {desc}\n{phase}"
> EOF
$ cp $HGRCPATH $TESTTMP/defaulthgrc
$ hg init repo
$ cd repo

$ echo "pushtobundlestore = True" >> .hg/hgrc
$ echo "[extensions]" >> .hg/hgrc

Understanding how data is stored on the bundlestore in server
-------------------------------------------------------------
There are two things, filebundlestore and index
$ ls ../repo/.hg/scratchbranches
filebundlestore
index
filebundlestore stores the bundles
$ ls ../repo/.hg/scratchbranches/filebundlestore/3b/41/
3b414252ff8acab801318445d88ff48faf4a28c3
index/nodemap stores a map of node id and file in which bundle is stored in filebundlestore
$ ls ../repo/.hg/scratchbranches/index/
nodemap
$ ls ../repo/.hg/scratchbranches/index/nodemap/
6cb0989601f1fb5805238edfb16f3606713d9a0b
$ cd ../repo
